The ‘druggable genome’ has been defined as those genes that can be pharmaceutically modulated; when intersected with disease-associated genes, the resultant set represents therapeutic targets for developing drugs to prevent and treat diseases. Historically, druggable therapeutic target genes have been defined by two features; (i) their significant contribution to the disease phenotype in a sufficient number of affected individuals and (ii) modulation of their activity by binding of a drug molecule.
The emerging era of cancer immunotherapy is dramatically changing the target landscape towards molecules that can be recognised by antibodies and T cells, thereby inducing redirection of immune effector mechanisms against target-bearing tumour cells. Despite the fact that the target space for immunotherapy is broad, few genes have been clinically evaluated as cancer immunotherapy targets. We have recently shown that patient and tumourspecific somatic mutations identified by next-generation sequencing of cancer genomes can be systematically targeted by cancer vaccines. In combination with a versatile immunotherapy platform for on-demand production of tailored vaccines, this, for the first time, opens the door to an entirely new source of druggable therapeutic targets – the abundant space of individual cancer mutations.

Researchers have identified several genes that may be implicated in the malaria parasite’s ability to rapidly evade drug treatments…
Recent advances in RNA interference (RNAi) technology and availability of RNAi libraries in various formats and genome coverage have impacted the direction and speed of drug target discovery and validation efforts. After the introduction of RNAi inducing reaagent libraries in various formats, systematic functional genome screens have been performed to query the functions of individual genes, pathways or an entire genome in many disease areas, including cancer, viral pathogenesis and others. As a consequence of these screens, novel mediators of cellular response to disease pathogenesis or treatment approaches have been identified leading to the discovery of novel drug targets, development of combinatorial treatment approaches and patient selection biomarkers.
Improved understanding of the molecular alterations in cancer cells has fuelled the development of more specific and directed cancer therapies. However, it has become clear that response rates can be low due to confounding genetic alterations that render these highly specific therapies ineffective. As a result, the costs of cancer treatment will increase enormously unless we are able to identify those patients that will benefit most from these directed therapies. In addition, it will be necessary to identify additional targets in these complex molecular networks that can be further exploited to increase overall response rates in the highly heterogenic populations of human tumours. In recent years, great expectations have been put forward for the use of functional genomic screening technologies to reach these goals.
It has been 10 years since the completion of the first draft of the human genome. Today, we are in the midst of a full assault on the human genetic code, racing to uncover the genetic mechanisms that affect disease, aging, happiness, violence … and just about every imaginable human variation. Advances in DNA sequencing technology have enabled individuals to have their own genomes sequenced rapidly, cheaply and in astonishing detail. The sequencing revolution is also changing the way the pharmaceutical industry develops, tests and targets new medicines.

TATAA Biocenters, located in Gothenburg, Sweden, Prague, Czech Republic, Freising outside Münich in Germany, and Sunnyvale, California1, work with leading instrument manufacturers and reagents companies in the quantitative real-time PCR (qPCR) field on new applications, making the know-how available through hands-on courses worldwide. Every year new courses are launched based on the most recent developments in the field. The year 2008 has been very active in the qPCR area, with several important advancements that provide solid ground for future development of new research and diagnostic tools.
One of the most profound advances in biology and medicine has been the sequencing of entire genomes, including the human genome. The end product was the availability of the complete genetic blue print of organisms of importance to medicine and biotechnology. This changed how we conducted science. Cloning individual genes was no longer a limiting factor. Instead, entire scientific communities set upon understanding how genes interact with each other in pathways and across pathways so as to explain complex biological and physiological processes. For the biotechnology and pharmaceutical industries, the identification, cloning, and engineering of a single gene to produce a key biological product such as erythropoietin, was no longer an attractive investment prospect. Instead, companies that produced either a clinically tested end-product, or provided entire platforms for high throughput screening, were the only ones being funded. The new benchmark for success is now speed and comprehensiveness, which are orders of magnitude greater than just ten years ago.
